To ail-whom it may cormcrn:

lie it known that .l Guoncn {lash thinncoxn'ucn. a citizen of the United States, residing at Ferguson, hlissouri, have invented a certain new and. useful lnun'oi 'ement in tar-l)oor-t)pesiting Mechanism, of which the following; is a full, clear, and exact descrintion. such as will enable others skilled in the art to which it appertains to make and use the san'iei reference being had to the accoin ainyingg drawings, forming part of this specification, in which-- Figure l is a to]; plan View of 21 portion ot a car I outed with my iinnrovml door opt-ratio ninisni. Fig. is a side ehvational View of the same. Fin. tional view on line i ----fi o'lhl ig q 52'. i" is a perspective view of one of the latching devices,

This in ention relates to a new and tlfiflilll inmrox'cmcnt in door operating); mechanism tor railway iiarticularly oi the damp or hopper bottom type, and has for its object in:provements in [mechanisms oi' this charm (er in general and particuhirly of that tvpe -.lisrloscii in United States Patent No. home? gin-tilted to .me January in 1908.

itethrring: to the drawings: l indicates one of the renter sill members of the car. :2 the door sheet 3 the side sill and l the side wall of the can The tloor sheet is provided with openin; ehrough which the contents of the car are tended to he discliargged, said ope n i s hein i closed by doors 5 one of which is shown in the drawings. "The door 5 is hing'ed'in asuitahle manner to the center sill ot the car and extends out to the side sill under which the free edge of the door is arranged, when closed, as shown. The door may he reii'ijt'orced by strengtheningangles in any appropriate manner and fixed to its free edge are bracket lugs or housings (3, ronstitiitnne pivotal supports for the latch- I These locks, as shown in detail in Fig. i, are each provitted on one side with a lateral extension 7 which cooperates with a projection 6* on the. bracket lug]; whereby the lock is prevented from swinging outwardly too far, swing inwardly as 'far as is necessary.

- lock has an inclined Wall 7" the outer surface of which is designed to heewinding shaft, 8 as the door raised to its closed position, thus causing; the loclt to swing inwardly until the lower curved edge twang and tend to closed position.

but is permitted to. .tween the two locks in raising the door to its Each against the 7 thereof is located above the shaft whercupon the lock is drawn outwardly by the winding chain, thereby locating the wall T above the shaft, as shown in Fig. 3. This wall l 1s slightl eccentric, the outer edge thereof being closer to the axis of movement of the loci; than is "the inner edge of said wall. In this manncig as the shaft 8 continues to rotate in raising the door, it will wedge the lock in place swinging the lock outwardly until a web 7 contacts with the shaft. H. The eccentricity of the hearing faces 7 is very slight and only sutlicient to insurecontact ot' the latching members with the winding shaft in cases where the sides oi the door are not drawn up equally.

Each door is provided with a pair of locks or latching devices and the members of each pa'c are connected by a bar or rail '12, the ends of, which are prefc'ahly attached in any suitable manner to downwardly extending walls or flanges 7, the same being formed inteii'ra-l with the lower portions oil? said locks. 'il his rail or bar performs the function of an equalizing bar and attached to an eye holt 13 at the w nter of the bar is one end oi a chain or cable 11, the other end of which altuchei-l to the winding shaft 8 As the winding shaftft optu'ated to wind the chain :11. thereupon, the free edge of the door is drawn upward past the winding shaft, and during this movement the inclined faces 7" of the locks or latching devices en gage against the winding shaftand said locksto pass said shaft must necessarily move inwai'l a short distance. As soon as the lower ends of the latching devices pass above the windin shaft, said latching devices will be drawn outward by the pull of the chain connected to the bar 12 and thus the hearing faces of the walls 7 will he drawn into engagement with the winding shaft, and the locks will hold the door in The winding chain or cable 11 is preferably attached to the center of the hat 12 and tihus said her becomes an equalizer to distribute the strain equalh hein my present construction the latches are 110 moved inward as the faces"? engage the winding shaft during the closing movement of the door.

It will be noted that the forward portion of the housings 6 extends over the upper end of the latch, and thus material such as Sand, crushed rock, coal and other foreign substances are prevented from dropping in behind the upper ends of the latches, and, thereby interfering with the swinging movements of said latches.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved door operating mechanism may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forthv in the appended claims.

lVhat I claim is: a a

1. In adoor operating mechanism the combination, of a door, a winding shaft, pivoted locking members carried by the free edge of the door for cooperating with the winding shaft when'th'e door is in'itsclosed position, said locking members being con" nected together and a flexible member attached to said shaft and to the connection between said locking members.

2. In a door operating mechanism the -combination,.of a door, a winding shaft, door locking devlces pivotally mounted on the free edge of the door and designed to co operate with the Winding shaft when the door is in its closed position, an equalizing bar connecting said devices and a flexible member attached to said winding shaft and said equalizing bar. a

3. In a door operating mechanism the combination, of a door, a winding shaft, latches pivctally, mounted on the free edge of the door for engaging the Winding shaft to lock the door in its closed position, which latches bear against the winding shaft'and are moved inwardly to pass said shaft during the closing movement of the door, a rigid connection between the lower portions of the gravity latches and afiexible member between said rigid connection and the winding shaft. p

l. In a door operating mechanism, the combination with a door, of a winding shaft, latches pivotally connected to the free edge of the door and adapted to cooperaterwith' Copies of this patent may be obtained for the winding shaft for supporting the door in its closed position, which latches are provided with eccentric shaft engaging faces,

a connection between said. latches, and a flexible connection between the winding shaft and the connection between said latches.

5. In a door operating mechanism, the combination with a door, of a winding shaft, door locking devices pivotally mounted on the free edge of the door and adapted to engage the winding shaft to hold the door in closed position, means for limiting the outward swing of said locking devices, an.

equalizing bar connecting said devices, and a flexible member attached to the winding shaft and said equalizing bar.

6. A door operating mechanism comprising a door, a winding shaft and connections for raising the door toits closed position, including a pair of pivotally mounted connected locking devices adapted to cooperate with the winding shaft to hold the door in closed position, which connected locking devices are drawn into engagement with the winding shaft by parts of the door raising means.

7. In a car door operating mechanism, the combination with a door, of a winding shaft and connections for raising the door to its closed position, including a pair of connected locking members pivotally mounted on the free edge of the door and adapted to engage the winding shaft to hold the door in closed position.

8. In a car door operating mechanism, the

combination with a door, of a winding shaft and connections for raising the door to it's closed position, including a pair of connected locking members pivotallv mountedengage the winding shaft to hold the door in closed position, which lockingmembers gre provided with eccentric shaft engaging aces.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses. tlr't; 26th day of September, 1911. M
